Title: Improvements in thread-rolling tool heads
Inventor: WAGNER KARL
IPC: B21H3/04
Filed: 1959-11-03
Abstract: 882,782. Rolling screw threads. WAGNER, E., and WAGNER, F., [trading as WAGNER MASCHINENFABRIK, GUSTAV]. Nor 3, 1959, No. 37240/59. Class 83 (4). In a thread-rolling head having three or more freely-rotatable annularly profiled roller dies arranged about the axis of the head and in which the axis of each of the rolls is slightly skew to the axis of the work and corresponding profiles are axially staggered from roller to roller by a fractional amount of the pitch equal to the reciprocal of the number of rollers, the leading rib profile of each roller is reduced in height so that when projected on to a common plane the crests of the leading profiles lie on an outwardly convex curve. The convex curve 6 is shown in Fig. 5 and in Fig. 6. The amount of reduction in height of consecutive crests is shown to be in geometrical progression. The rolls have profiles reduced in height at each end so that the work may be fed between the rolls in either direction or the entire head may be reversed.
